Michigan State University engineering prof, student design helmet inserts to help drown out crowd noise for QBs.

3D-printed helmet earhole insert helps drown out noise for some players on the school's football team.

Michigan State's starting quarterback Aidan Chiles and linebacker Jordan Turner have helmets with inserts.

XO Armor Technologies provides on-site, on-demand 3D printing of athletic wearables.

About 60 teams across college football and the NFL wearing the inserts.

“The Big Ten has some pretty impressive venues,” Kolpacki said.

“It can be just deafening,’ he said. “That's what those fans are there for is to create havoc and make it difficult for coaches to get a play call off.” Bush called the inserts a “win-win” for everyone.
